This bug is an upstream one and it would be quite helpful if somebody experiencing it could send the bug the to the people writing the software. You can learn more about how to do this for various upstreams at https://wiki.ubuntu.com/Bugs/Upstream/GNOME . Thanks in advance!

I ran some tests. First, with Karmic Koala Live-CD and Gimp 2.6.7. I've attached a screenshot. I noticed that Gimp in Lucid has not only lost his Progressbar in the Statusbar but also the two Dropdownfields. Have look on the attached Karmic-Screenshot and you will see.

I've generated a debdiff for the developers review so they can patch the Ubuntu package with it. I've tested it and it's working. I have also uploaded the patched version to my ppa for those who don't wish to wait :) My ppa is at: ppa:gastly/gastly-main

Accepted gimp into lucid-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!
